'ro ALL wHoM 1T MAY ooNo'ERN;

"Bc it` known that I, HENRY HULL, of Pattersonvilleparish of St. Marys, and Stato of Louisiana, have made certain new and useful improvements in Moss-Carding Machines; and I do hereby declare the following to be a full, clenrgand exact description of the same', reference being had to the annexed drawings, making a part of this' specication, i

My invention consists of the combination of an upper convex swinging or vibrating card, with a lower or inferior fixed or stationary concave card, when the teeth of both said upper and lower cards project at a small angle with reference to the axis of the upper card, and in the same direction, and areV so placed that in the operation -of the machine there can be no contact between them.

On the drawings, A is the upper vibrating card, supported 'by frame B, and having 'tsfaxis at a. In this card the teeth, it will be seen, project towards the right. C is the fixed concave ',card', which is permanently secured to frame The teeth c of this card also project toward the right, 4and. at the same angle as the teeth on the upper card. The machine delineated upon the drawings is a hand machine, requiring two laborers eilicientlyto work it; Vonetogive it motion,the other to feed it. At proper intervals these laborers alternate with one another, in order. 'that the one who operates .the machine may not be tasked too severely. The handles d enable the operator to-give'motion to the upper card A.

In the operation' of themachine 'an armful of moss is thrown cn apron D by one attendant, whilst the other rapidlyvibrates the upper card A by means of the handles d. 'The teeth-in the upper card pointing from the apron D, pass 4through the moss lying thereupon without removing it, as the 'card swings overthe apron, and on that very account on the return `swing'they catch among its fibres and 4force it upon,l and over card 'C until it reachesthe ven d of theV same, where it falls off, completely cleaned. and ready for use. As soon as card A swings o` apron D, a. fresh supply of moss is thrown upon the latter, andso :onV at every vibration of card A. If a'ny moss clings to the teeth o f the upper card, the tee'tlrofl cardC remove it, as theformer swings again towards apron D, and in the return vibration itis swept off and deposited at the end of the machine.' The dirt and trash fall through card C as fast as the mossv is freed of it. I have found by experience `that this simple machine, worked by two men,'wil1 clean as much mossl as eight men by the ordinary process that is practised in this part of the country, and in a far more thorough and complete manner. If it be desired to have a larger machine than can beworled by hand, nothing is easier than to make such an adaptation of proper gearing as will permit steam orother power to be applied without changing the principles of the handemachine I have described in any particular. l

Having thus described my invention, what I claim and desire to patent, is

The vibrating convexecard A, in combination with the fixed concave card C, when the teeth of both project in the same direction und at the vsame,.angle as described for the purpose set forth.
